tools: per-strate density dispatch report in the fast tier (L132)

--density-dispatch-report prints each strate's bound path and tile shares. Owner world: SW native heightfield;
FI, TN, VS on compiled-analytic legacy fallback (FI lacks an imported FloatingIslandPlan; TN/VS have legacy recipes).
A native FI candidate broke the composed owner walk/shell gates, so the owner stays on its path. Output unchanged.

+# L132 — owner density dispatch
+
+## Result
+
+With Core enabled in the owner headless pipeline, the four strates bind to four paths. Unreal’s `bUseVoxelForgeCore` remains opt-in and defaults off. The fast-tier diagnostic reports the Core bindings at the four L80 owner poses and attributes hashed tiles by tile-center height within the resolved stratum bounds.
+
+| Strate | Owner recipe | Bound path | Tile centers / share |
+|---|---|---|---:|
+| SW (0) | `SurfaceWorld.Heightfield2D` v2 | `SurfaceWorld-native` | 2,640 / 100% |
+| FI (1) | `FloatingIslands.ClusterField` v0 | `compiled-analytic/FloatingIslands` | 2,128 / 100% |
+| TN (2) | `legacy.TunnelNetwork` v0 | `compiled-analytic/TunnelNetwork` | 2,208 / 100% |
+| VS (3) | `legacy.VerticalShafts` v0 | `compiled-analytic/VerticalShafts` | 1,392 / 100% |
+
+SW has a matching strate/bounds `SurfaceWorld` plan, and its `Heightfield2D` evaluator is valid. FI has a legacy v0 layout record but no matching `FloatingIslandPlan`, so `FloatingIslandFieldV1` cannot bind. The Core owner manifest has zero island plans. TN and VS have legacy recipe IDs, not `Core.Caves.PrimitiveField` v1 or `Core.Lattice.PrimitiveField` v1. Their resolved layouts therefore lack the matching graph recipe and native-field capability. All three fall through to `FLegacyGeneratorFieldAdapter`.
+
+The dispatch check is in the fast tier and can also be requested from the headless binary with `--density-dispatch-report`. It prints the per-strate bound adapter/path and hashed tile-center path shares. Its tile counts aggregate the four standard owner poses; tiles whose centers fall outside an interior interval are excluded, and a tile spanning a boundary is assigned by its center. Per-view logs are `Saved/Linux/l132/owner-density-dispatch-s*-clang.log`; the printed shares are in `Saved/Linux/l132/logs/verify-fast.log` and `Saved/Linux/l132/fast-summary.json`.
+
+Across the 8,368 classified tile centers, path shares are 31.5% SurfaceWorld-native, 25.4% compiled-analytic/FloatingIslands, 26.4% compiled-analytic/TunnelNetwork, and 16.6% compiled-analytic/VerticalShafts.
+
+## Native FI decision
+
+The native evaluator is present. `BuildFloatingIslandStratumPlan` can convert the owner’s legacy island parameters to a v8 plan, but the owner’s imported manifest does not contain that plan. The existing automatic-plan branch is guarded by `bImportedOverride` inside the generated-assembly branch, so it does not fill this owner’s missing imported plan.
+
+I built a candidate v8 plan for the existing owner FI strate without changing the default owner data. Its raw island-route audit passed: 29 route points, 78,336 capsule samples, zero blocked samples, zero unsupported probes, and zero grade failures. The composed owner audit did not pass:
+
+- Existing compiled-analytic owner: all 3 passage interfaces pass; shell floor violations 0; ripple checks 3/3.
+- Native FI candidate: only 2/3 interfaces pass; the added FI route is not walkable (1/2 strate routes walkable); shell floor violations 13; ripple checks 2/3.
+- Passage tile seams passed for both bindings: 4 pairs, 4,900 shared samples, zero mismatches.
+
+Native FI is a quality regression on the owner’s current passages, despite its standalone route plan passing. I did not switch the owner. The conditional captures, W8/W12 timing matrix, and Clang/GCC W1/W8/W12 matrix were not run because the candidate failed the composed walk/shell gate. No Core version or output baseline changed; the default owner output remains on its existing bindings. No Linux UE host build was run because there was no qualifying native change or timing matrix.
+
+## TN/VS graph translation size
+
+The active TN `GenerationParams` block has 47 fields; VS `VerticalShaftParams` has 11. Each also has 15 passage settings. Both have `CoreGeometry.GeneratorRecipe=0` and empty `Rooms`, `Tunnels`, and `Stamps` arrays. Native cave/lattice authoring requires at least one explicit room and one edge, with geometry, links, and route data. There is no adapter translating those legacy generator blocks into graph records. This is a substantial procedural migration, not a small recipe mapping, so I did not build it this round.
+
+## Verification
+
+- Fast tier: PASS, 304.0 s, 84 runs and 273 checks; includes four-pose dispatch output.
+- Passage tile seams: compiled-analytic and native FI candidate both PASS at the FI owner pose.
+- Owner walk/shell comparison: default PASS; native candidate FAIL as detailed above.
+- Build stamp: `766b94ca7638475975b0345e5907eebb96158360c384f5d916c78eccbb1aa815`.
